WIREDRAWING BLOCK.

Application filed July 19, 1922. Serial No. 576,053.

To all whom it may concern:

Be it known that I, CARL E. TIDEMAN, a citizen of the United States, residing at Worcester, in.-the county of NVorcester and.

State of Massachusetts, have invented a new and useful Niredrawing Block, of which the following is a specification.

to provide an effective and practical way of cooling the drums so that the heat generated from the successive passage of the wires through a series of dies will be com pensated for at the drums. Therefore, the wires will not be heated up more and more as it passes along from die to die in a'con- 'tinuous wire drawing machine.

Reference is to be had to the accompany ing drawings, in which ig. 1 is a plan of a wire drawing drum with a preferred embodiment of this invention applied thereto;

Fig. 2 is a central sectional'vert-ical view of the same; a

Fig. 3 is a plan of the water supplying device in the drum; and

Fig. 4 is a transverse sectional view on the line 4-4 of Fig. 3. i

I am aware of the fact that it is well known that continuous wire drawing machines require .the cooling of the drums for the reason that, as the wire passes each die considerable heat is generated.

(srdinarily, without water cooling," the temperature of the wire gradually increases by its passage through the several dies until it is so hot that it is injured by the process. The principal idea of this invention is to provide improved means whereby the drums can be cooled adequately without expensive alterations. For this purpose I have shown a modified drum 10 for re-.

wire from a die. 'It is mounted ceiving the on a vertical shaft 11. The outside of this drum is notmaterially modified but the.

bottom 12, which connects the hub 13 on 'the' vertical shaft 11-with thev outside, is

raised at the circumference. This provides an external triangular annular groove 14 at the bottom, opening at the lower side of the drum. The drum is shown as usual considerably wider at the bottom than atthe top and has this space 14 directly behind the conical surface on which the lower coils of wire are wound. This wire is heated to the highest degree and if properly cooled the wire at the top will not become overheated. This'groove 14 can be made, if desired, by, welding two conical flanges in the bottom of a drum having a fiat bottom. And I conical anges 23 and 22 below the groove.

For the purpose of dissipating the heat,

the table or bench 15 is provided with acircular tank 16 in which is located a distributing pipe 17 of acircular shape receiving the water from any source of supply through an inlet 18 and discharging it through an annular passage or outlet 19 which may extend all the way around the circle directly under the open bottom groove 14. This annular distributing pipe 17 is supported at one side by the integral inlet pipe, 18 which has been'desc'ribed. It is referto employ in addition two w shown, opposite the inlet. 18 as supplied with diverging feet 21 for firmly support-1 ing it in horizontal position in the tank 16.

Thisdirects a circular sheet of water up into contact with the interior. surfaces of the groove and supplies a constant flow of water all around the drum, which is rotating all the time. The water thus discharged falls back into the tank 16 and is allowed to drain off through an outlet 20. The flange 23 prevents the water being discharged inside and the flange 22 prevents its being forced outside by centrifugal force. The pipe distributes water to the groove 14 at all times diiring the wire drawingl operation. This prevents the cumulative ing ofi'th wire to such an extent as to injure the dies.

I have described this process of cooling eata drum of a continuous wire drawing machine, but the invention is not limited to a continuous wire drawing apparatus. I

do not wish to be limited to the" use of this inventionfor continuous wire drawing ma chine, as' it is of great value for other similar wire drawing drums.

. Although I have illustrated and described only one ormbf the invention, I am aware of the fact that modifications can be made.

therein by those skilled in the art without departing from the spirit and scope thereof as expressed in the claims, therefore, I do not wish to be limited to all the details herein described but what I do claim 1. The combination with a rotary wire drawing drum, of a water distributing pipe located below the bottom thereof, and having an annular outlet opening extending toward the drum upwardly, and means for directing water into distributing pipethereby forcing it against the external lower surface of the drum. v

2. The combination with a wire drawing drum having a conical outer surface, and an annular external groove at the bottom thereof behind the conical surface for receiving the wire, of a central distributing pipe lo cated a distance below it, and having an annular outletfor discharging the 'water into the groove throughout the circumference thereof. r i

3. The combination with a conical wire drawing drum having an external inverted V-shaped thereof an open at the bottom, the lower groove surrounding the bottom part of the conical wall of the drum constituting the outer Wall of said groove, and a means for directing a circular sheet of water into said groove to cool the bottom of the drum.

4. The combination with a wire drawing drum having a pair of circular diverging external flanges extending downwardly at the bottom forming a circular groove between them, of means for forcing a circular sheet of water between the 'flanges.

5. As an article of manufacture, a wire drawing drum having a conical external surface at the bottom for receiving wire and a pair of diverging circular flanges on the outside of the bottom" thereof behind said conical surface.

6. As an article of manufacture, a drum for receiving wire 'thereon'having an external circumferential groove in the bottom thereof and extending both above and below the surface on the dr um for receiving the first coil of Wire.

In testimony whereof I have hereunto aflixed my signature.

CARL E. TIDEMAN.
